ABSTRACT
— Network has become a significant way to transmit information because of the arrival of information era and the rapid development of Internet. Various multimedia digital products (such as text, images, videos, sound data, etc.) spread on the net. How to protect the benefit of the investors and legal rights owners is becoming an upcoming problem to solve. In this couple of years, the data encryption/decryption (modern cryptography) technique develops rapidly, which can provide a new effective approach to deal with this problem. In this paper a strong time efficient cryptosystem is proposed. A novel approach in cellular automata is used in which the plain text is arranged into layers of binary digital planes and then encrypted based on the rule set of Automata. This scheme exhibits strength by inheriting the naive properties of Cellular Automata, unpredictability, homogeneity, parallelism and sensitivity to the initial conditions. The proposed scheme is analyzed for time efficiency and observed to possess better confusion and diffusion properties when compared with Advanced Encryption Standard (AES). This scheme has advantage, that it has variable key size and block size; depending on the size of the plain text chosen. Simulation results show that the proposed system is on par with AES.
